@uablrek, would you be willing to propose this as a blog article for https://k8s.dev/? It feels like it's aimed at a contributor audience.
If it's published there, we'll be happy to mirror it here (approval is implicit).
|
@sftim I will. I assume it's here https://github.com/kubernetes/contributor-site/tree/master/content/en/blog ? A reason for non-developers to know this is the possibility to actually handle a difficult traffic use-case with a |

That is the target audience for https://k8s.dev/: people who want to contribute to Kubernetes. I think writing an alternative proxy could count as a contribution, but equally you could use the information in this article to write your own proxy that you don't publish as a project contribution. |

I am a bit unsure if links are allowed in the initial paragraph. No other blogs seem to have them.
@sftim Is it allowed?

"internal load-balancer" can lead to confusions with the Service with Type LoadBalancer, it is more like "the default Kubernetes Services implementation" or something like that.

sounds nice to me 👍 |

I leave out the "easily". Granted that the API stuff hadled by kpng is easy, but load-balancing is certainly not 😄

@kubernetes/sig-network-misc how's this article looking? I'm looking for a reassurance that there's nothing in here where, once published, we'd want to yank the article or immediately update it. |
|
I have updated after review, but I still wonder if there is a better place for the example. A place where k8s examples are collected maybe? Where/who can I ask? |
|
But https://github.com/Nordix/kpng-example is perfectly fine for me, and if it's ok please publish. |
|
Could that example live within https://github.com/kubernetes-sigs/kpng/tree/master/examples ? If not, I wonder if we could get a repo https://github.com/kubernetes-sigs/kpng-examples and make a branch / directory there for this example? |
|
I'll check https://github.com/kubernetes-sigs/kpng/tree/master/examples. The only problem would be that I want to build the example out-of-tree. But perhaps it's ok if it can be copied. I'll be back... |
|
The example is copied to https://github.com/kubernetes-sigs/kpng/tree/master/examples/pipe-exec, and the link in the post updated. |

This is ready for a review; SIG Docs blog team can re-add LGTM after setting a publication date. |

Shall I squash the commits and change the file name? And make a force push. |
@uablrek Yes, that will work |

@reylejano Done: rename, squash, rebase and force-push |

Adds a blog post about the sig/network kpng project and how it can be used to create specialized proxiers to handle traffic use-cases not supported by K8s.
The post is intended for anyone and is kept short (no TL;DR). However for developers a more in-depth example is provided.
readable post
About the example
The example is currently hosted on https://github.com/Nordix/kpng-exampleMoved to https://github.com/kubernetes-sigs/kpng/tree/master/examples/pipe-exec
The example will be updated quite often to keep in pair with the
kpngdevelopment.
